The person detector majestic's object detection runs on the CPU of
cameras without an NPU (HiSilicon/Goke parts with the IVE motion
backend): an int8 network majestic's own engine loads from
/usr/share/majestic/person.pdnet, with the thresholds of its three
presets beside it in person.json. 84 KB. MIT.
The int8 networks majestic's own engine runs on the CPU, in
/usr/share/majestic:
- person.qnet, the person detector its object detection runs on
cameras without an NPU (HiSilicon/Goke parts with the IVE motion
backend), with the thresholds of its three presets beside it in
person.json;
- drum.qnet, which reads the drums of a water, gas or electricity
meter for its meter reading.
134 KB together. MIT.
